MultiRAE Equipped with A Pump
With its pump speed setting of low or high, a MultiRAE normally draws in air at a flow rate of
between 200 cc/min and 300 cc/min. RAE Systems recommends that a calibration adapter
used with calibration gas flow rates from 500 cc/min to 1000 cc/min.
Installing the Calibration Adapter
WARNING: Make sure the calibration adapter clips on and stays in the correct position during
calibration, as illustrated below. Otherwise, the calibration adapter must be manually held in
the correct position.

MultiRAE Lite Diffusion Model (No Pump)
Because there is no single inlet on the diffusion (non-pumped) version of the MultiRAE, a
Calibration Adapter is used for supplying calibration gas to all sensors at one time. Follow these
steps for attaching the Calibration Adapter (PN M01-3010-003 pack of 3).
